Pretty printing of JSON responses is important to be able to understand
large responses from query commands in particular. Unfortunately this
was broken during the addition of the verbose flag in

  Author: John Snow <jsnow@redhat.com>

    scripts: qmp-shell: Add verbose flag

This is because that change turned the python data structure into a
formatted JSON string before the pretty print was given it. So we're
just pretty printing a string, which is a no-op.

The original pretty printer would output python objects.

(QEMU) query-chardev
{   u'return': [   {   u'filename': u'vc',
                       u'frontend-open': False,
                       u'label': u'parallel0'},
                   {   u'filename': u'vc',
                       u'frontend-open': True,
                       u'label': u'serial0'},
                   {   u'filename': u'unix:/tmp/qemp,server',
                       u'frontend-open': True,
                       u'label': u'compat_monitor0'}]}

This fixes the problem by switching to outputting pretty formatted JSON
text instead. This has the added benefit that the pretty printed output
is now valid JSON text. Due to the way the verbose flag was handled, the
pretty printing now applies to the command sent, as well as its response:

(QEMU) query-chardev
{
    "execute": "query-chardev",
    "arguments": {}
}
{
    "return": [
        {
            "frontend-open": false,
            "label": "parallel0",
            "filename": "vc"
        },
        {
            "frontend-open": true,
            "label": "serial0",
            "filename": "vc"
        },
        {
            "frontend-open": true,
            "label": "compat_monitor0",

Support ARM big-endian ELF files in system-mode emulation. When loading
an elf, determine the endianness mode expected by the elf, and set the
relevant CPU state accordingly.

With this, big-endian modes are now fully supported via system-mode LE,

endianness so the ifdeffery on TARGET_WORDS_BIGENDIAN goes away.

Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.

The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.

As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

If the user passes us an EL3 boot rom, then it is going to want to
implement the PSCI interface itself. In this case, disable QEMU's
internal PSCI implementation so it does not get in the way, and
instead start all CPUs in an SMP configuration at once (the boot
rom will catch them all and pen up the secondaries until needed).
The boot rom code is also responsible for editing the device tree
to include any necessary information about its own PSCI implementation
before eventually passing it to a NonSecure guest.

(This "start all CPUs at once" approach is what both ARM Trusted
Firmware and UEFI expect, since it is what the ARM Foundation Model
does; the other approach would be to provide some emulated hardware
for "start the secondaries" but this is simplest.)

This is a compatibility break, but I don't believe that anybody
was using a secure boot ROM with an SMP configuration. Such a setup
would be somewhat broken since there was nothing preventing nonsecure
guest code from calling the QEMU PSCI function to start up a secondary
core in a way that completely bypassed the secure world.

The virt board restricts guests to only 30GB of RAM. This is a
hangover from the vexpress-a15 board, and there's no inherent reason
for it. 30GB is smaller than you might reasonably want to provision
a VM for on a beefy server machine. Raise the limit to 255GB.

We choose 255GB because the available space we currently have
below the 1TB boundary is up to the 512GB mark, but we don't
want to paint ourselves into a corner by assigning it all to
RAM. So we make half of it available for RAM, with the 256GB..512GB
range available for future non-RAM expansion purposes.

If we need to provide more RAM to VMs in the future then we need to:
 * allocate a second bank of RAM starting at 2TB and working up
 * fix the DT and ACPI table generation code in QEMU to correctly
   report two split lumps of RAM to the guest
 * fix KVM in the host kernel to allow guests with >40 bit address spaces

The last of these is obviously the trickiest, but it seems
reasonable to assume that anybody configuring a VM with a quarter
of a terabyte of RAM will be doing it on a host with more than a
terabyte of physical address space.

Since the incorrect expression was always true, this just meant that
commit cb01d391 had no effect.

However simply changing the RHS here would reveal a logic error: if
the mode is USR we wish to completely ignore the attempt to set the

to avoid the uncached_cpsr bits being updated at the end of the
